2 CHANNEL 10/100/1000 MBPS ETHERNET
ELECTRICAL TO OPTICAL MEDIA CONVERTER
The ComNet Ethernet CNMC2+1SFP electrical-to-optical Ethernet media converters
accept two 10/100 or 1000 Mbps electrical inputs and converts this to a single 100
or 1000 Mbps optical output (selected by a DIP switch) and the 100/1000 Mbps
optical input back to the 10/100/1000 Mbps electrical output. “Auto-Negotiating” is
supported on the copper interface side. These devices use either one or two optical
fibers, depending upon the selection of sold-separately SFP optical module. The
ComNet exclusive Demux feature allows for port isolation, replicating two media
converters over one fiber. The ComNet exclusive Mux feature prevents network video
flooding of multicast traffic with DIP switch selection of the fiber port as a dedicated
uplink path. The CNMC2+1SFP series can be powered by wide range of AC or DC input
power supplies.
LED indicators confirm operational status. All models are environmentally hardened
with no electrical or optical adjustments (Plug and Play). DIP Switches on the outside of
each unit allow for fine-tuning of features. See Figures 1 – 12 for complete operation
details. See Figures A and B for mounting instructions.

Link Fault Pass-Through Enabled.If the Copper Port is Down or Not Connected, the
Optical Port will turn on and off at a ~1 sec rate to indicate copper port 2 fault.
3 FFE Fiber Fault Relay Disabled
Fiber Fault Relay Enabled. If the optical link is lost or there is a power failure then the alarm
relay output will be triggered.

Mux Enabled. All Ethernet traffic is diverted from the copper ports to the fiber port,
copper-to-copper traffic will be disabled.

DeMux Enabled. When two CNMC2+1SFP units are connected via fiber and both have
DeMux enabled, traffic from Port 1 will go to Port 1 and traffic from Port 2 will go to Port 2
only, functioning like two separate media converters over one fiber.

The fault relay is normally closed and will open on any of the following alarm conditions:
- Link Fault is enabled on the remote CNMC2+1SFP unit and a copper port has been disconnected.
- Link Fault is enabled on the local CNMC2+1SFP unit and a copper port has been disconnected.
- Fiber Fault is enabled on the local CNMC2+1SFP unit and the fiber link is down or the power has been lost
to either the local or remote CNMC2+1SFP unit.

MECHANICAL INSTALLATION INSTRUCTIONS
INSTALLATION CONSIDERATIONS
This fiber-optic link is supplied as Standalone/Surface Mount and Surface
Mount/Rack Mount modules. Units should be installed in dry locations
protected from extremes of temperature and humidity.
C1-US, C1-EU, C1-AU or C1-CH Card Cage Racks
CAUTION: Although the units are hot-swappable and may be installed
without turning power off to the rack, ComNet recommends that
the power supply be turned off and that the rack power supply is
disconnected from any power source. Note: Remove electrical connector
before installing in card cage rack.
1. Make sure that the card is oriented right side up, and slide it into the card
guides in the rack until the edge connector at the back of the card seats in
the corresponding slot in the rack’s connector panel. Seating may require
thumb pressure on the top and bottom of the card’s front panel.
CAUTION: Take care not to press on any of the LEDs.
2. Tighten the two thumb screws on the card until the front panel of the
card is seated against the front of the rack.
WARNING: Unit is to be used with a Listed Class 2 power supply.
IMPORTANT SAFEGUARDS:
A) Elevated Operating Ambient - If installed in a closed or multi-unit rack
assembly, the operating ambient temperature of the rack environment may
be greater than room ambient. Therefore, consideration should be given to
installing the equipment in an environment compatible with the maximum
ambient temperature (Tma) specified by the manufacturer.
B) Reduced Air Flow - Installation of the equipment in a rack should be such
that the amount of air flow required for safe operation of the equipment is not
compromised.
